WATER-GAGE.

SPECIFICATION forming part of Letters Patent N0. 788,030, dated April 25, 1905.

Application filed July 26,1904. Serial No. 218,226.

Be it known that I, CrrARLnYR. ELLIOTT, a r'esident of Denver', in the county of Denver' and State of Colorado, have invented cer'tain new and useful Improvements in Tater- (nragesg and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable otlrer's skilled in the art to which it appertains to make and use the same.

My invention r'elates to an improved water'- gage for steam-boilers, the object of the invention being' to provide improved mechanism for automatically preventing the escape of steam and hot water in the event of br'eaking the glass tube and to so construct the parts as to permit the glass tube to be inserted from above or below without disturbing the metal fixtures.

\\'ith these and other objects in view the invention consists in certain novel features of construction and combinations and arrangements of par'ts, as will be mor'e fully hereinafter descr'ibed, and pointed out in the claims.

In the accompanying'drawings, Figure 1 is a view in side elevation, illustrating my inrpr'overnents. Eig. 2 is a view in ver'tical section. Fig. 3 is a view in vertical section on the line ,fr .r of Fig. 2, and Fig. 4 is a view of the safety or automatic valve removed.

1 represents the upper and 2 the lower metal tixture, having' threaded ends 3 for attachment to the boiler. Both fixtures 1 and 2 are made with angular enlarged casings 4 and internally-threaded sleeves 5 opposite the opening communicating with the boiler', and threaded valve-stems 6 are mounted lin said threaded sleeves and ar'e adapted to close said openings, and enlarged handholds 7 ar'e located on the outer ends of the stems to facilitate their' oper'ation.

Integral with the angular' casings 4 and at one side thereof are vertical alined sleeves 8, suitably packed to receive the glass tube 9. The upper end of upper' sleeve 8 is closed by a threaded plug 10, and the lower end of lower' sleeve 8 is closed by a threaded cock 11, either of which can be removed and the glass tube inserted or removed from above or below through either' of said sleeves 8.

The casings 4 are made with ports 12, permitting the free passage of water and steam to the tube 9, and a screw 13 is located in lower' sleeve 8 and projects thereinto below the end of tube 9, limiting the downward movement of said tube and holding it above the port 12, so as not to interfere with the free passag'e of water, this scr'ew being removed or unscrewed slightly when the tube is to be removed orinser'ted through the lower' sleeve 8.

In casing 4 in both of the fixtures flapvalves 14 are mounted, and said Hap-valves 14 normally hang in a vertical position adjacent to ports 12 and ar'e supported on hanger's 15, having trunnions at` their ends supported in notches in the casing, and said valves can be readily removed and replaced through openings in the top of the casings, which ar'e normally closed by threaded plugs 16, and threaded plugs 17 close openings in the sides of the casings which permit ready inspection of the par'ts when desired.

In the Ordinar-y operation of the gage the valves 14 hang idle, due to the uniform pressure throughout; but should the glass tube break the pressure behind valves 14 will force them to their' seats and close ports 12, pr'eventing' the escape of hot water and steam. The broken tribe can be removed through the upper sleeve 8 by removing plug' 10 or through the lower sleeve 8 by removing cock 11, and the new tribe can be inserted through either' the upper' or lower sleeve, as may be desired.

A great many slight changes might be made in the general form and arrangement of the parts described without departing from my invention, and hence I would have it understood that I do not restrict myself to the pr'ecise details set forth, but consider' myself at liberty to make such slight changes and alter'- ations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is*- 1. In a gage, the combination with two HX- tures, each having a sleeve, a glass tube connecting said sleeves, lremovable devices closing said sleeves and permitting the insertion and removal of the glass tube through either sleeve, said liXtures having lateral chambers communicating with the sleeves, and flapvalves in said chambers and designed to automatically close communication with theA sleeves when the tube breaks.

2. In a gage, the combination of two lixtures, each having a sleeve and each having a chamber laterally removed from the sleeve and communicating therewith` a glass tube mounted at its ends in said sleeves, andremovable deviees closing the outer ends of said sleeves, and permitting the insertion and removal of the glass tube through either sleeve, a manually-operated valve carried by each fixture for shutting off Communication between the fixtures and the boiler, and automatic {lap-valves mounted in said lateral chambers for closing communication between said chambers and the sleeves carrying the tube, when the latter breaks.

3. In a gage, the combination of two fixtures, each comprising a Chamber and a sleeve arranged side by side and Communicating with each other, means permitting the insertion of a gagetube through either of said sleeves, each chamber having an opening in its top, plugs in said openings, and Hap-valves suspended from said plugs and adapted to automatically close communication between said chambers and sleeves when thev gage-tube breaks.

In testimony whereoi1 I have signed this specification in the presence of two subscribing witnesses` CHARLEY R. ELLIOTT.
